Tapered roof insulation details.

Standard material is johns manville enrgy 3tapered and flat polyisocyanurate roof insulation. However tapered lightweight insulating concrete should be evaluated as an alternate to tapered insulation as it may be more efficient due to the roof configuration details and location.
